Use the BeginUpdate method to maintain performance when editors are added to the control one at a time. Use the DataSource property to bind a recordset to the control.

The following VB sample adds 10 EditType editors in the control:

With Record1
   .BeginUpdate
   Dim i As Long
   For i = 1 To 10
    .Add "Editor <b>" & i & "</b>", EditType
   Next
   .EndUpdate
End With

The following VC sample adds 10 EditType editors in the control:

m_record.BeginUpdate();
for ( long i = 1; i < 10; i++ )
{
	COleVariant vtMissing; vtMissing.vt = VT_ERROR;
	CString strLabel;
	strLabel.Format( "Editor <b>%i</b>", i );
	CEditor editor = m_record.Add( COleVariant(strLabel), /*EditType*/ 1, vtMissing );
	editor.SetValue( COleVariant( i ) );
}
m_record.EndUpdate();
